Tl P FOR ELECTRIC CONDUCTORS.

SPECIFICATION forming part of Letters Patent No. 533,910, dated February12, 1895.

Application filed November 26, 1894:- Serial No. 29,89 (No model-) Toall whom it may concern.-

. Be it known that I, AMANDUS METZGER, a

' citizen of the United States, residing at Schenectady, in the countyof Schenectady, State of New York, have invented certain new andv are tobe joined to permanent contacts of any kind; and has for its object toprovide a tip which shall be a ready means of making such an electricalconnection asI have referred to,

and which shall, while alfordin g ample contact area for both the conducting cable or wire and the'connection to the fixed or permanentcontact, at the same time be constructed cheaply both as regards amountof material therein and the labornecessary to make the tip.

To the ends pointed out I form my tip of a strip of sheet copper orother good conduct- Y in g material, and in its preparation I first forma blank having a body portion composed of two similar parts adapted toregister with each other when bent about a central line, an extensionwhich may-be bent into the form ofa tube for encircling the conductor,at the same time being upset so that the bottom line of the conductor issubstantially in the plane of the body part of the tip, and a third partconsisting of two small lugs or lips which, when the similar parts ofthe body portion of the strip are brought together, may be wrappedaround the extension or tube for the conductor, locking the wholeconstruction securely. All the steps in this process may be readilyperformed mechanically and the entire construction of the tip is withinthe width of a "single strip of copper.

The accompanying drawings show an embodiment of my invention, Figure 1showing the blank as at first made; Fig. 2 a plan View, Fig. 3 a sideelevation, and Fig. 4 an end elevation, of my improved conductor tip.

Referring by letter, A is the base or body portion of the tip, composedof two similar trapezoids A, A registering with each other when the baseis bent on the line Ct-Qt.

B is the extension adapted to form the tube encircling the conductor.

C, C, C, C are cut-away portions or nicks inclosing insulation.

lugs securing it in place.

- D is the end portion having the lugs D, D

for the purpose already pointed out in the statement of invention.

In Figs. 2 and 3, the completed conductor tip is shown and in this casea hole E is shown also provided for the 'bolt adapted to secure theconductor to the permanent contact; and in Fig. 2 G represents theconductor with its In these figures F represents the distortion orupsetting of the metal of the part A. The object of this is to move theconductor above the plane of the two parts facilitating the bending ofthe tube and of the A, A so that its bottom may be .approximately in theplane of those two parts, and thus a flat contact may be assured, aswhen the conductor has to pass over a plane surface of any kind and beaffixed to a contact in the plane of that surface.

' In Fig. 4. I show in end view the same parts shown in Fig. 3. It willbe seen that the lugs D, D are slightly longer than is necessary to passacross the center of the tubular portion B, so that they-embrace alittle more than half the circumference of the tube. By the constructiondescribed I attain the ends of lightness, cheapness, and good electricalcontact, so much to be'desired in devices of this class.

Where I use the term permanent contact, I do not necessarily mean tolimit myself to the use of my conductor tip-in this relation, as it maybe used in any manner for which it is adapted, and still be within thescope of the claims.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is

1. As a new article of manufacture, a blank for the formation of aconductor tip, comprising a body portion composed of two similar figuresadapted to register when the body part is bent about its center, anextensionfrom such body part and an end portion provided with lugsadapted to be wrapped about the extended portion when the conductor iscompleted.

2. As a new article of manufacture, ablank for the formation of aconductor tip, comprising a central body portion composed of two similarfigures adapted to register when the body portion is bent about itscentral line, an

extension atone end of such body portion, an end part at the other endof the body portion provided with lugs, and nicks or cuts between thebody part, extension and end portion.

3. As a new article of manufacture, a conductor tip formed of a singlepiece of metal comprising a flat portion doubled upon itself, and a tubeformed integrally with the flat portion for embracing the conductor end.

4. As a new article of manufacture, a tip for an electrical conductor,comprisinga fiat part provided with means forsecuring it to the contact,a tube for the conductor formed intogrally with the flat portion, andlugs formed integrally with the flat portion, adapted to embrace thetube.

In witness whereof I have hereunto set my hand this 24th day ofNovember, 1894.

AMANDUS METZGER. Witnesses:
